The Effect of Obstructive Sleep Apnea and Its Treatment on Decision Making
Obstructive Sleep ApneaObstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.
Surgical Treatment of Children With OSA and Small Tonsils or Down Syndrome
Obstructive Sleep Apnea of ChildThe purpose of this study is to prospectively compare the effectiveness of a novel personalized approach to the surgical treatment of obstructive sleep apnea (OSA) in children, drug induced sleep endoscopy (DISE) directed surgery versus the standard adenotonsillectomy (AT). This will also serve to test the feasibility of recruiting families for a future randomized protocol comparing the same surgical techniques. It is the investigators' central hypothesis that a personalized DISE-directed surgical approach that uses existing procedures to address the specific fixed and dynamic anatomic features causing obstruction (ie, anatomic endotypes) in each child with small tonsils or Down syndrome will be superior to the currently recommended standard first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT. To test this hypothesis, the investigators will study children aged 2 to 18 years with clinically small tonsils (Brodsky score 1+ or 2+ on a scale 1+ to 4+) OR Down syndrome.

The Role of Sleep Disordered Breathing in Heart Failure Admissions
Sleep Apnea SyndromesHeart FailureThe purpose of this study is to evaluate the effect of in-hospital diagnosis and treatment of sleep disordered breathing (SDB) on post-discharge mortality and readmissions in- hospitalized patients with acute heart failure syndrome and reduced ejection fraction (HFrEF).
Influence of Exercise, Weight Loss, and Exercise Plus Weight Loss on Sleep Apnea
Obstructive Sleep ApneaOverweightObstructive sleep apnea (OSA) is highly prevalent among Veterans, and is associated with significant mortality and multiple morbidities. Available treatments have had limited effectiveness in treating OSA and alleviating associated morbidity. The investigators' previous research found a reduction in OSA severity of approximately 25% following modest exercise training. That this effect occurred independent of weight loss raises the exciting possibility that exercise combined with weight loss could reduce OSA by at least 50% and have unique health benefits for OSA patients. Following screening and baseline assessments, 90 overweight Veterans ages 18-60 years with OSA will be randomized to one of three 16-week treatments: (1) exercise training; (2) 10 % weight loss; and 3) exercise + weight loss. Changes in OSA and related morbidity will be compared between treatments.
Comparison of Two Oral Appliances in the Treatment of Sleep Apnea Syndrome
Obstructive Sleep ApneaMonocentric comparative group study comparing the efficacy and short-term tolerance of a propulsion type oral appliance (Herbst) with a retention type device (ORM) used in the treatment of sleep apnea syndrome. The investigators hypothesized both appliances would be equally effective and tolerated.
A Trial to Evaluate a Device for the Treatment of OSA and Snoring
Obstructive Sleep ApneaSnoringTo evaluate the safety and efficacy of the Tongue Advancement Retainer Device in treating subjects with Obstructive Sleep Apnea (OSA) and snoring.
Obstructive Sleep Apnea Treatment to Improve Cardiac Rehabilitation
Obstructive Sleep ApneaCoronary Heart DiseaseThis is a randomized clinical trial in U.S. Veterans to evaluate the impact of treatment for obstructive sleep apnea (OSA) on the effectiveness of cardiac rehabilitation, including impact on exercise capacity, disability, and quality of life.
In-Hospital Portable Sleep Monitoring for the Evaluation of Obstructive Sleep Apnea (OSA)
Obstructive Sleep ApneaHypothesis: Portable sleep testing of hospitalized medical inpatients suspected of having OSA is accurate in determining the need for positive airway pressure (PAP) therapy when compared to outpatient laboratory-based polysomnography. Hospitalized medical inpatients referred for suspected OSA will be tested with a portable sleep apnea testing device during hospitalization. These patients will then undergo an outpatient laboratory-based attended polysomnography after hospital discharge. Results of the inpatient portable sleep apnea test will be compared to the outpatient laboratory-based polysomnography in terms of diagnostic accuracy.
